Processor
You can upgrade the processor to take advantage of future options in speed
and functionality. The processor and its associated internal cache memory are
contained in a land grid array (LGA) package that is installed in a ZIF socket
on the system board.
Replacing the Processor
CAUTION: Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. Before performing any
procedure, see your Product Information Guide for complete information about
safety precautions, working inside the computer and protecting against
electrostatic discharge.
1
Open the system. See "Opening the System" on page 54.
NOTICE: Never remove the heat sink from a processor unless you intend to remove
the processor. The heat sink is necessary to maintain proper thermal conditions.
NOTE: When you remove the heat sink, the possibility exists that the processor
might adhere to the heat sink and be removed from the socket. It is recommended
that you remove the heat sink while the processor is still warm.
2
Remove the cooling shroud. See "Removing the Cooling Shroud" on
page 56.

Using a #2 Phillips screwdriver, loosen the four captive screws that secure
the heat sink to the system board. See Figure 3-18.
